Important Notes
The watch includes one CR2 battery, which may be used during manufacturing or initial setup.

Care should be taken to avoid prolonged exposure to water beyond splash resistance, and the leather strap should be kept dry to preserve its condition. Always refer to official Swatch guidelines for maintenance and servicing to ensure longevity.
